Also, Found this great playlist a while back on blender modelling for goldsrc (note that these tutorials were made before this new tools option so you can skip the converter steps):https://www.youtube.com/playlist?lis...2peExsuPk3gYWNAlso, a newer tutorial on making an animated helicopter.

Blender is kinda wierd to get used to (im a max user) but it is rising in popularity among modders ive seen.One thing I should add is that if your model looks like a jumbled mess of verticies upon compile its likely that you had 2 or more bones per vertex set in blender. If you are still having export issues, you can try going back to exporting using the peterthegoats source to goldsrc converter (in the youtube playlist).
